Error when installing e2guardian on a fresh install of pfSense

[CocoBanane55]

Hello,

First of all thanks you to give us an Unofficial e2guardian on pfSense.

When I want to install e2guardian, after patching the system, it give me this error :

Fatal error: Uncaught TypeError: count(): Argument #1 ($value) must be of type Countable|array, null given in /usr/local/www/e2guardian.php:171

Debug information:
I'm on pfSense 23.01 based on FreeBSD 14 RELEASE (pfSense+ subscription for non-profit organization).
I take the patch for 2.7 version as it is based on FreeBSD 14 too (maybe the problem I prefer to notice)

Thanks you in advance for you help

For me, I just replace the line 171:

if (count($config['installedpackages']['e2guardianblacklistsdomains']['config']) > 18) {

for this:

if (($config['installedpackages']['e2guardianblacklistsdomains']['config'] != null) && (count($config['installedpackages']['e2guardianblacklistsdomains']['config']) > 18)) {

pfSense 23.05.
